This is SCIENCE FRIDAY. I'm Flora Lichtman. This next segment is specially dedicated to people for whom midsummer means lush greens, maybe a little sand and hopefully a lot of birdies. We're in the thick of golf season. The U.S. Open wrapped up last month, the British Open last weekend. And in just a few weeks, the PGA Championship begins. Up next, a look at the science of this sport. What sets the pros apart? Stroke mechanics, swing thoughts, physics, psychology?
Reporting in Science, researchers write of linking a mouse's innocuous memory of a room with a more fearful memory of getting an electric shock — causing the mouse to freeze in fear upon seeing the safe room. Study author Steve Ramirez of M.I.T. and memory researcher Mark Mayford of The Scripps Research Institute discuss the implications for modifying human memories.
It's high summer, yes, but blink and soon it will be fall, and trees will turn red, brown, beige, yellow, pale green and gold. But not cars. Cars may be making the Earth warmer, but their colors, I notice, have turned wintry.

Bill Stone is a maverick cave explorer who has plumbed Earth's deepest abysses. In this talk, he explains what it's like to descend into the deepest caves in complete darkness for days on end — and why he keeps doing it.
Explorer Ben Saunders wants you to go outside. Not because it's always pleasant and happy, but because that's where the meat of life is, "the juice that we can suck out of our hours and days." In 2004, Saunders skied solo to the North Pole. Saunders' next outdoor excursion? To try to be the first in the world to walk from the coast of Antarctica to the South Pole and back again.
From madness to seizures, to crime and lack of sleep, people have long blamed the full moon for a range of problems. Research, on the other hand, has found little evidence over the years to support these anecdotal accounts of the moon's powers over the human body and brain.
But scientists in Switzerland decided to look again at one of those putative effects — disturbed sleep — and were surprised to see there might be something to the claim after all.

Come summertime, some of us here at Shots are reminded, as we lounge on decks and venture into overgrown gardens, that we are irresistible to mosquitoes.
